Circuit Documentation

Summary of the Circuit

The circuit described is a simple AC power circuit designed to control an AC bulb using a rocker switch. The circuit is powered by a 220V AC power source. The rocker switch acts as an on/off control for the AC bulb. When the switch is in the "on" position, the circuit is closed, allowing current to flow through the bulb, illuminating it. Conversely, when the switch is in the "off" position, the circuit is open, and the bulb is not illuminated.

Documented Code

There is no embedded code provided for this circuit as it does not contain any programmable components or microcontrollers. The operation of the circuit is purely electrical and mechanical, based on the physical position of the rocker switch.


This documentation provides an overview of the circuit's design and functionality, along with detailed information about the components and their wiring. If any updates or modifications are made to the circuit, the documentation should be updated accordingly to reflect those changes.
